Dyne Pens – 38 Dynes/cm Pen Set

The 38 dynes/cm test pen is a quick method of determining if a surface has been pretreated with corona or plasma surface treatment. The test pen is used as any other felt tip pen. If the line drawn on the surface to be tested is continuous, the material has been pretreated at no less than 38 dynes/cm and will accept ink, paint and adhesives. If the line is interrupted, and the dyne ink beads up the surface has been poorly treated or not treated at all.
